Luxembourg
Luxembourg's employment routes: an authorisation to stay must be obtained before entering, and the first permit runs a maximum of one year restricted to a single profession and a single sector, opening up only on renewal. The EU Blue Card is exempt from the labour market test but carries a salary threshold set by Grand-Ducal regulation.
How the system works
Step 1: The authorisation to stay must be obtained before entering
The order cannot be reversed in Luxembourg: a third-country national must obtain the authorisation to stay from abroad before entering to take up work. The response time is normally a maximum of four months, and the temporary authorisation that results is valid for 90 days. Several months therefore need to be allowed between filing and actually starting, and entering on another basis to switch on the spot is not the route.
Step 2: The employer declares the vacancy to ADEM and obtains a certificate
The employer must first make a declaration of vacant position to the National Employment Agency (ADEM). If no suitable candidate has been presented within three weeks of that declaration, the employer may request a certificate from ADEM's director allowing recruitment of a third-country national. The employer hands the original certificate to the applicant, who attaches it to the authorisation-to-stay application. Those three weeks are a fixed wait in the process and cannot be compressed.
Step 3: Note that the first permit is confined to one profession and one sector
This is the most underestimated restriction in Luxembourg: the first residence permit is valid for a maximum of one year and covers one profession only, within a single sector, though with all employers in it. On first renewal the permit becomes renewable for a maximum of three years and gives access to any sector and any profession. In practice there is very little room to change field during that first year, and the choice is effectively locked in at application.
Step 4: Highly qualified applicants can take the EU Blue Card instead
The EU Blue Card is for highly qualified work, requires an employment contract of at least six months, and requires an annual salary at least equal to the amount set by Grand-Ducal regulation. Its key advantage is that highly qualified workers are not subject to the labour market test, so the three-week ADEM check does not have to be waited out — though the employer must still declare the vacancy to ADEM. The first Blue Card is valid for four years, or for the duration of the contract plus three months where that contract runs less than four years.

What commonly blocks an application
These are frequent reasons a route is closed. Absence of a listed problem is not an eligibility decision.
Entering first and trying to switch afterwards. Luxembourg requires the authorisation to stay to be obtained before entry, and that order cannot be reversed.
Underestimating the timeline. The authorisation-to-stay response alone normally takes up to four months, on top of the three-week ADEM wait before it.
Planning to change field or sector during the first year. The first permit covers one profession within one sector and only opens up on renewal.
Assuming the Blue Card removes ADEM entirely. What it removes is the labour market test; the employer's vacancy declaration still applies.
Planning against a remembered Blue Card salary figure. The amount is set by Grand-Ducal regulation and revised, so the figure in force at application must be confirmed.
